Abstract
La présente invention est relative à un procédé pour la préparation d'oligosaccharides. Ce procédé est caractérisé en ce que l'on élimine pratiquement tous les olisosaccharides en dessous d'un poids moléculaire minimum désiré, à partir d'un échantillon contenant un mélange d'oligosaccharides, en traitant simultanément ledit échantillon par une levure et une amylase. Application d'oligosaccharides ainsi obtenus comme substrats pour le dosage des amylases.The present invention relates to a process for the preparation of oligosaccharides. This process is characterized in that practically all olisosaccharides below a desired minimum molecular weight are removed from a sample containing a mixture of oligosaccharides, by simultaneously treating said sample with yeast and amylase. Application of oligosaccharides thus obtained as substrates for the assay of amylases.
